  • Patent number: 8848688
    Abstract: A method and system for using a handoff threshold associated with a slot cycle index to determine whether to perform access terminal handoff from a current pilot signal to a target pilot signal. The determination may be conditioned on whether the current pilot signal and target pilot signal are transmitted from base stations within a common subnet. If the base stations are within a common subnet, handoff of the access terminal is based on a default handoff threshold. On the other hand, if the base stations are not within a common subnet, then the determination of whether to perform access terminal handoff from a current pilot signal to a target pilot signal may be made based on the handoff threshold associated with the slot cycle index. As a result, ping-ponging of the access terminal from one subnet to another may be reduced or prevented.

  • Patent number: 8848703
    Abstract: A table for changing destination has a destination address in a shared memory and an identifier of a router directly connected to a destination core, in association with each other, and is set by a source core. A search unit performs a first search for searching whether the table has an effective entry having the same address as the destination address in the shared memory, and stored in a header of a write request packet received by the source core. A route calculation unit performs a route calculation with a destination that is a router of an identifier of the entry, if the effective entry is found as a result of the first search. A header generator stores the router identifier obtained by the route calculation in a hop router field of the header of the write request packet, and sets a rerouted flag representing a change in destination.

  • Patent number: 8848707
    Abstract: Prefix length memory tables are used to enable fast IPv4 LPM lookups using a single memory access for a first range of IP prefixes, and using two memory accesses for larger IP prefixes. Each of the prefix length memory tables is used to hold a set of forwarding rules associated with a different prefix length range. IP LPM operations are then performed in parallel in each of the prefix length memory tables of the set, and the forwarding rule matching the longest prefix is returned from each of the memory tables. A priority encoder is used to select between positive results from the multiple prefix length memory tables to enable the forwarding rule with the largest matching prefix to be used to key into the next hop forwarding table. The method utilizes low cost DDR SDRAM rather than TCAM, and also exhibits low overhead.

  • Patent number: 8848709
    Abstract: Methods and apparatus for source rooted multicast (SRM) are provided. As defined herein, SRM generally refers to associating outgoing interface lists (OILs) in the forwarding entry with the source address instead of the group address and aggregating the resulting multicast forwarding states. In this manner, the amount of forwarding state may be reduced, especially in deployments where many hosts are all running the same application and using the same group. One example method generally includes—for each of a plurality of multicast forwarding states associated with a multicast group, wherein each multicast forwarding state is referenced by a source address representing a multicast source and is associated with an outgoing interface list—associating the outgoing interface list with the source address; and aggregating the two or more of the multicast forwarding states having the outgoing interface lists associated with the source addresses to form one or more aggregated forwarding states.

  • Patent number: 8848710
    Abstract: The present invention is directed towards a method and system for providing a technique referred to as flash caching to respond to requests for an object, such as a dynamically generated object, from multiple clients. This technique of the present invention uses a dynamically generated object stored in a buffer for transmission to a client, for example in response to a request from the client, to also respond to additional requests for the dynamically generated object from other clients while the object is stored in the buffer. Using this technique, the present invention is able to increase cache hit rates for extremely fast changing dynamically generated objects that may not otherwise be cacheable.
